Solve this multiple-choice question and choose the correct option.

Genetics (molecular control of heredity): The inherited traits of an organism are primarily controlled by which molecules? Identify the long-term information-storage polymer in cells. Choose the correct option.

Difficulty: Easy

RNA molecules
Nucleotides
DNA molecules
Enzymes

Correct Answer: DNA molecules

Explanation:

Concept/ApproachDNA encodes genetic information; genes (DNA segments) determine inherited traits. RNA participates in expression; nucleotides are monomers; enzymes are proteins catalyzing reactions.

Final AnswerDNA molecules

Bohr–de Broglie relation: The number of standing de Broglie waves fitting an electron’s circular orbit equals the principal quantum number n. If the maximum magnetic quantum number is +3 (so l = 3), determine the number of waves for the lowest allowed orbit with that l. Choose the correct option.
Avogadro comparison (atoms vs. molecules): Match the number of atoms in a given silver sample to an equivalent count of molecules in another substance. 21.6 g of silver is given; use atomic weight Ag = 108 g/mol to find moles and hence number of atoms. Choose the option whose sample contains the same number of molecules as atoms in the silver sample.
